German WWII K98 Mauser restoration

I got a good deal on a somewhat rare variant of the K98K. This rifle was made in the last days of WWII (serial number would point toward late February or early March 1945 by Gustloff Werke (receiver code BCD) Apparently these were produced using forced labor from the Buchenwald Concentration camp. It has many of the late war or "Kreigsmodell" characteristics (Lack of a bolt takedown disc in the stock, stamped and welded barrel bands, lack of serialized parts etc) The parts that are serialized (bolt, bolt parts and barrel) all match. The floor plate, trigger guard and follower are all marked correctly. It has that "just out of the attic" look to it, some very light surface rust that should clean up with some Kroil. The bore is in fantastic shape, although i probably won't shoot this much. My main concerns are the rear sight base and front sight.. looks like someone tried to remove them a long time ago (perhaps to make a sporter) and then put them back on, butchering the rear sight base in the process. Here is a quick "before" picture. Im going to take it apart later when i get home and see what I'm in for.
